OpManager is a powerfull tool easy to setup and even easier to use, the set up dosn`t take more than 30 minutes, and it feel like a out of the box solution for networks monitoring.
With OpManager we are able of keep track of any alarm on all our physical and virtual servers, no matter the operative system that is running, OpManager just need the credentials for that machine or device, and in a few minutes you can start to see relevant information about your enviroment.
Right now, our infrastructure is not so big, and we are monitoring a few servers and network devices, but OpManager fit perfectly to our needs, because let us know what is really happening with our network
With the network devices, right know we are able to see netflow data of two network interfaces, but OpManager let us monitor a lot more.
Something that i really like is that if you don`t know how to configure Netflow in your router, OpManager can do it for you, just provide OpManager with the device credencials and it will take care of that with zero complications.
OpManager is very scalable and fits perfectly to any small business or large enterprise.
I don`t know if does not exist that feature, but i can`t find the way to backup the OpManager configuration automaticaly, they have a documented process in thier website, but is a manually process and leave margin for a human error.
It should improve or add that feature in next releases.
